Two races of the periodical cicada exist. One race has a life cycle of 13 years and is common in the southeastern United States. The other race has a life cycle of 17 years and is generally more orthern in distribution. Due to Tennessee’s location, both the 13- year and …

W127 Common Beneficial Arthropods Found In Field Crops, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

There are hundreds of species of insects and spiders that attack arthropod pests found in cotton, corn, soybean and other field crops. A few common and representative examples are presented herein. With few exceptions, these beneficial arthropods are native and common in the southern United States. The cumulative value of insect predators and parasitoids should not be underestimated, and this publication does not address important diseases that also attack insect and mite pests. Without biological control, many pest populations would routinely reach epidemic levels in field crops. Insecticide applications typically reduce populations of beneficial insects, often resulting in secondary pest …
